• Searching for a key in a multi dimensional array and adding it to another array [migrated]

  - by Moha

  Let's say I have two multi dimensional arrays: array1 ( stuff1 = array ( data = 'abc' ) stuff2 = array ( something = '123' data = 'def' ) stuff3 = array ( stuff4 = array ( data = 'ghi' ) ) ) array2 ( stuff1 = array ( ) stuff3 = array ( anything = '456' ) ) What I want is to search the key 'data' in array1 and then insert the key and value to array2 regardless of the depth. So wherever key 'data' exists in array1 it gets added to array2 with the exact depth (and key names) as in array1 AND without modifying any other keys. How can I do this recursively?

• Chinese hosting and domain registrar

  - by Tak

  A client has asked me to develop and host a website in China (I'm in Europe). I'm looking for a reliable English-speaking hosting company and domains provider in China. Shared hosting will be sufficient with PHP/MySQL on linux servers. Finding a reliable hosting company can be difficult, especially abroad. I wonder, does anyone have experience with Chinese hosting companies? Is there a big "main player" like UK2 or GoDaddy? Thanks

• Are Java servers really more preferable for web-development? [closed]

  - by Gerald Goward

  Many experienced people I know tell me that many web-projects, including enterprise ones, are better to develop with Java being back-end. Reasons: Ubuntu servers being cheaper and more reliable. MySql being much more "light" rather than "heavyweighted" MS Sql. I heard some more, but I really cant remember all of them. My question: I believe ASP.NET and Java are BOTH good for web-development and its just holywar subject. Am I right or not?

• Does the Adblock Plus extension prevent malicious code from downloading/executing? [closed]

  - by nctrnl

  Firefox and Chrome are my favourite browsers. The main reason is an extension called Adblock Plus. Basically, it blocks all the ad networks if you subscribe to one of the lists, like EasyList. Does it also protect against malicious ads on completely legitimate websites? For instance, several news websites use ad services that may allow a malicious user to insert "evil code". This makes the web very unsafe, especially for those who lack a serious antivirus product.

• Questions about identifying the components in MVC

  - by luiscubal

  I'm currently developing an client-server application in node.js, Express, mustache and MySQL. However, I believe this question should be mostly language and framework agnostic. This is the first time I'm doing a real MVC application and I'm having trouble deciding exactly what means each component. (I've done web applications that could perhaps be called MVC before, but I wouldn't confidently refer to them as such) I have a server.js that ties the whole application together. It does initialization of all other components (including the database connection, and what I think are the "models" and the "views"), receiving HTTP requests and deciding which "views" to use. Does this mean that my server.js file is the controller? Or am I mixing code that doesn't belong there? What components should I break the server.js file into? Some examples of code that's in the server.js file: var connection = mysql.createConnection({ host : 'localhost', user : 'root', password : 'sqlrevenge', database : 'blog' }); //... app.get("/login", function (req, res) { //Function handles a GET request for login forms if (process.env.NODE_ENV == 'DEVELOPMENT') { mu.clearCache(); } session.session_from_request(connection, req, function (err, session) { if (err) { console.log('index.js session error', err); session = null; } login_view.html(res, user_model, post_model, session, mu); //I named my view functions "html" for the case I might want to add other output types (such as a JSON API), or should I opt for completely separate views then? }); }); I have another file that belongs named session.js. It receives a cookies object, reads the stored data to decide if it's a valid user session or not. It also includes a function named login that does change the value of cookies. First, I thought it would be part of the controller, since it kind of dealt with user input and supplied data to the models. Then, I thought that maybe it was a model since it dealt with the application data/database and the data it supplies is used by views. Now, I'm even wondering if it could be considered a View, since it outputs data (cookies are part of HTTP headers, which are output)

• Javascript - is this a grey area for anyone else?

  - by Anonymous -

  I have a firm understanding of HTML, CSS, PHP, MySQL (and to some extent apache/linux) and find that one of the things missing from my 'web development knowledge base' is javascript - creating richer user interfaces. I'd like to learn Javascript before I look at any frameworks (I've used light javascript/jquery before, but that's besides the point). Can anyone recommend a firm book or online documentation from 'absolute beginner' to 'expert' for javascript? I seem to be finding too many 'display the time' and 'hello world' tutorials...

  I'm looking for something fairly simple for clients to use and very easy for me to skin (somewhat complicated themes). something like Perch or Couchcms, but has to be open source to satisfy some license requirements.. I can't really seem to find any CMS that is like this {Wordpress, drupal etc are way too heavy for this use} , really appreciated There aren't much requirements, anything will really work - each site gets their own jailed instance and stuff, just PHP/MySQL

• In a state machine, is it a good idea to separate states and transitions?

  - by codablank1

  I have implemented a small state machine in this way (in pseudo code): class Input {} class KeyInput inherits Input { public : enum { Key_A, Key_B, ..., } } class GUIInput inherits Input { public : enum { Button_A, Button_B, ..., } } enum Event { NewGame, Quit, OpenOptions, OpenMenu } class BaseState { String name; Event get_event (Input input); void handle (Event e); //event handling function } class Menu inherits BaseState{...} class InGame inherits BaseState{...} class Options inherits BaseState{...} class StateMachine { public : BaseState get_current_state () { return current_state; } void add_state (String name, BaseState state) { statesMap.insert(name, state);} //raise an exception if state not found BaseState get_state (String name) { return statesMap.find(name); } //raise an exception if state or next_state not found void add_transition (Event event, String state_name, String next_state_name) { BaseState state = get_state(state_name); BaseState next_state = get_state(next_state_name); transitionsMap.insert(pair<event, state>, next_state); } //raise exception if couple not found BaseState get_next_state(Event event, BaseState state) { return transitionsMap.find(pair<event, state>); } void handle(Input input) { Event event = current_state.get_event(input) current_state.handle(event); current_state = get_next_state(event, current_state); } private : BaseState current_state; map<String, BaseState> statesMap; //map of all states in the machine //for each couple event/state, this map stores the next state map<pair<Event, BaseState>, BaseState> transitionsMap; } So, before getting the transition, I need to convert the key input or GUI input to the proper event, given the current state; thus the same key 'W' can launch a new game in the 'Menu' state or moving forward a character in the 'InGame' state; Then I get the next state from the transitionsMap and I update the current state Does this configuration seem valid to you ? Is it a good idea to separate states and transitions ? And I have some kind of trouble to represent a 'null state' or a 'null event'; What initial value can I give to the current state and which one should be returned by get_state if it fails ?

• Best sources to find your go-to programmer

  - by user66851

  After exhausting many resources, time, interviews etc, I cannot seem to find the correct programming talent for our company. Any other resources you suggest besides Dice, Linkedin, Craigslist, University Job Boards, Poaching techniques....its been months now! Specifically, we designed proprietary data-manipulation and data-gathering technology, and are looking for skilled programmers requiring skills of PHP5/MySQL, Javascript/HTML/CSS , cross-browser compatibility/optimization, web interface development, familiarity with source control (SVN or GIT), any L/AMP stack, and/or related application protocols, GCC-supported languages, Zend Framework and/or jQuery.

• Creating advanced website by redirecting and replacing content from Google Sites

  - by David

  I would like to create a corporate website with members area. Importantly, I want many novice webadmins to be able to modify static content themselves. Therefore, I got the idea to create the site using Google Sites and insert elements with width and height in places where I want dynamic content. The website would be read using PHP on a different server and the marker elements would be replaced with dynamic content created by PHP. What would be the drawbacks of this approach?

• Using HBase or Cassandra for a token server

  - by crippy

  I've been trying to figure out how to use HBase/Cassandra for a token system we're re-implementing. I can probably squeeze quite a lot more from MySQL, but it just seems it has come to clinging on to the wrong tool for the task just because we know it well. Eventually will hit a wall (like happened to us in other areas). Naturally I started looking into possible NoSQL solutions. The prominent ones (at least in terms of buzz) are HBase and Cassandra. The story is more or less like this: A user can send a gift other users. Each gift has a list of recipients or is public in which case limited by number or expiration date For each gift sent we generate some token that uniquely identifies that gift. For each gift we track the list of potential recipients and their current status relating to that gift (accepted, declinded etc). A user can request to see all his currently pending gifts A can request a list of users he has sent a gift to today (used to limit number of gifts sent) Required the ability to "dump" or "ignore" expired gifts (x day old gifts are considered expired) There are some other requirements but I believe the above covers the essentials. How would I go and model that using HBase or Cassandra? Well, the wall was performance. A few 10s of millions of records per day over 2 tables kept for 2 weeks (wish I could have kept it for more but there was no way). The response times kept getting slower and slower until eventually we had to start cutting down number of days we kept data. Caching helps here but it's not an ideal solution since a big part of the ops are updates. Also, as I hinted in my original post. We use MySQL extensively. We know exactly what it can and can't do both in naive implementations followed by native partitioning and finally by horizontally sharding our dataset on the application level to reside on multiple DB nodes. It can be done, but that's not really what I'm trying to get from this. I asked a very specific question about designing a solution using a NoSQL solution since it's very hard to find examples for designs out there. Brainlag, not trying to come off as rude. I actually appreciate it a lot that you are the only one who even bothered to respond. but I see it over and over again. People ask questions and others assume they have no idea what they're talking about and give an irrelevant answer. Ignore RDBMS please. The question is about nosql.

• What shall I include in a 10 week web technologies course?

  - by Iain

  In September I will be teaching a university module on web technologies. This session will be available to 1st year (freshman) students who don't necessarily have any programming knowledge or know how the web works. In the 2nd semester I will be teaching Flash, which is my specialism, so I know exactly what I am going to teach, but in the 1st semester I will be teaching them web standards technologies - HTML, CSS, JS, jQuery, PHP and MySQL. Where I need advice is how to proportion the emphasis for each part, and which parts of each technology to cover. Another real issue I'm struggling with is how much of the bad old ways should I teach them? Do they need to know about bold as well as strong, etc. UPDATE: based, on your feedback I will only be teaching the latest version of everything - CSS3, HTML5 etc. I'm not sure exactly how long the semester will be but I'm guessing about 10-12 weeks. Each session is a 2 hour lab. Obviously there's only so much I can cover in that time and it will be up to the students to go a research this stuff properly on W3 schools etc. My ideas so far were: Lesson 0 - Course intro and overview of the current tech landscape. What is out there, what will we be learning, what won't we. What is a web server, URL etc. Looking at different example websites and discussing how they work. Lesson 1 - HTML basics (head, body, title, img, table, a, lists, h1, strong etc) Lesson 2 - CSS for styling and layout - fonts, webfonts, float etc Lesson 3 - Intro to programming JS (variables, loops, conditionals, functions) Lesson 4 - more JS programming fundamentals, DOM manipulation Lesson 5 - jQuery - making things fly about and look cool Lesson 6 - XML and Ajax Lesson 7 - PHP basics - syntax, server-side principles Lesson 8 - PHP and MySQL - forms, logins, saving user info Lesson 9 - don't know Lesson 10 - don't know Please let me know if you think this is the right order, what have I missed, how to use any spare sessions etc. Thanks :) UPDATE BASED ON RESPONSES: Thanks for all your responses - some great stuff. To be absolutely clear, this is not a computer science course, it is a practical module on a creative technology course. The emphasis definitely has to be on making cool things work rather than understanding how the backbone of the internet works. That can come later, if the students are interested. At the end of the module I would like the students to be able to produce a web page or pages that does something cool, using some or all of the technologies I cover. Many of these topics are of course far beyond the scope of a 2 hour session, however I do not have the option of reducing the syllabus, I will just have to explain what the technology does and encourage the student to research it in their own time.

I am not sure which container is best for the job - list, vector or something else?

A kernel/driver conflict perhaps? I don't see any processes in R or D state that might inflate the load averages artificially, I realise it may be considered low in an 8 thread system but its higher at idle than any normal behaviour I've previously come across. Thanks in advance for your time.
